Alexa keeps on saying Sonos One is offline

Finally got it sorted, appears the phone app simply wasn't working. I'd set the skills, and it would show offline. I logged into the alexa.amazon.com page, and it showed no skill setup but the device was online. So I added the skill via the online portal... and boom. Works perfectly.

Thanks SHutchinson - I did this and it worked - The Sonos Skill was missing from Alexa.amazon.com account. Once I added the Skill and linked it with Sonos (which happened like a workflow once I clicked enable). Alexa now seems to be able to play Radio from Tunein, turn up and down the volume, pause music (activated by the Sonos App Manually). However as Im an Apple Music Subscriber - She can't play anything.

Glad this solved some of your issues. The apple issue I have no idea about, I assume it's functionality problem, as the Sonos can't do Spotify either yet (gets added 21st December). Believe it's some "exclusivity" with Amazon driving that, basically making the device such a hassle to use, you're forced to buy an Amazon Music subscription. It's a shame, but I'll just wait it out and use it as a glorified radio until then. If I'm not careful with my words, Alexa basically just says "Your Amazon Music account isn't setup properly"... What's also annoying is you can't change the default music options away from Amazon to Tunein for the radio, so you have to specifically include Tunein in your requests... I understand why they make technology harder to use, so they can force sales off people, but that doesn't make it ok.

I had the same issues and it was driving me insane.

After a call with the support team at Sonos we went through all of the above but actually found out the issue was a setting on my amazon account

He said I would need a computer to access certain settings but you can do this on an iPhone by requesting a desktop version of the site.

Once you do that go to settings, content and devices and check all is ok there and you can see your devices. Then click settings then see the country settings section. My has the country as “unknown”

So for me the issue was that I didn’t set a country! Once I set that then asked Alexa to play the radio it did! And through the Alexa app my Sonos turned from offline to online.

All sorted! Hope that helps

I set up my Sonos and Alexa with the room named as Bathroom everything worjked great until I changed the room name to Bedroom (bath is in bedroom). Changed it on Sonos and Alexa app but my sonos kept saying it was offline. Seems my sonos is still registered as Bathroom on my amazon account... couldn't work out how to change this so just renamed it back to Bathroom on Sonos and and Alexa and hey presto, working fine again!

If you change the name of an Alexa Device, you will at least need to select Alexa App>Smart Home>Devices>Discover. As long as you haven't set-up any Routines within the Alexa App, the best approach is to open the Alexa App on a PC via https://alexa.amazon.co.uk or .com and select Smart Home>Devices and then scroll to the bottom of the list and select 'Forget All' followed by 'Discover'. Your renamed device should now work as normal.

All sorted! Hope that helps

That finally helped. Sonos, put this in your FAQ. Drove me nuts until I found this hack. Wonder how to know that it is necessary to set the language/country in my Amazon account.

After three days of trying to get my Sonos One showing as On-Line in my Alexa Android phone App, I logged onto my Alexa account using the PC app. I didn't change anything using the PC app, but the Sonos One just magically was showing as On-Line. I then checked my phone Alexa app and it was the same. I can now play music through the Sonos One using Alexa. Brilliant but perplexing.

Yes, the PC Alexa app, although limited in it's functionality, still appears to be able to resolve problems that the Android and iOS app can't fix.

I was bashing my head against a wall about this Alexa offline issue until my daughter pointed out there’s a mic on/off button on top of the Sonos: One. Sorted! To be fair, it does just look like an LED.

To be fair, it does just look like an LED.That's a different issue. This is not about having the mic muted. it's about Alexa refusing to connect to skills and services, like the Sonos skill.

Apologies, Nellie. Thought that was too easy a fix. Yes, have failed to connect Alexa to many skills. 😕
